Dr. Maem Hussein's Thoughts

Confirming that RR can be an alternative to R chemotherapy as a first line therapy  in advanced stage follicular lymphoma.

ABSTRACT

The RELEVANCE trial (ClinicalTrials.gov identifier: NCT01650701) showed that lenalidomide plus rituximab (R2) provided similar efficacy to rituximab plus chemotherapy (R-chemo) in patients with advanced-stage, previously untreated follicular lymphoma (FL). We report the second interim analysis of the RELEVANCE trial after 6 years of follow-up. Patients with previously untreated grade 1-3a FL were assigned 1:1 to R2 or R-chemo, followed by rituximab maintenance. Coprimary end points were complete response (confirmed/ unconfirmed) at week 120 and progression-free survival (PFS). At median follow-up of 72 months, 6-year PFS was 60% and 59% for R2 and R-chemo, respectively (hazard ratio 5 1.03 [95% CI, 0.84 to 1.27]). Six-year overall survival was estimated to be 89% in both groups. Median PFS and overall survival were not reached in either group. Overall response after progression was 61% and 59%, and 5-year estimated survival rate after progression was 69% and 74% in the R2 and R-chemo groups, respectively. The transformation rate per year in the R2 and R-chemo groups was 0.68% and 0.45%, and secondary primary malignancies occurred in 11% and 13% (P 5 .34), respectively. No new safety signals were observed. R2 continues to demonstrate comparable, durable efficacy and safety versus R-chemo in previously untreated patients with FL and provides an acceptable chemo-free alternative.

Axicabtagene Ciloleucel as Second-Line Therapy for Large B-Cell Lymphoma

In this international, phase 3 trial, we randomly assigned, in a 1:1 ratio, patients with large B-cell lymphoma that was refractory to or had relapsed no more than 12 months after first-line chemoimmunotherapy to receive axicabtagene ciloleucel (axi-cel, an autologous anti-CD19 chimeric antigen receptor T-cell therapy) or standard care (two or three cycles of investigator-selected, protocol-defined chemoimmunotherapy, followed by high-dose chemotherapy with autologous stem-cell transplantation in patients with a response to the chemoimmunotherapy).
